A couple months ago I discovered a really cool site: Yelp. It's like a Citysearch that doesn't suck. Although the site covers cities nationwide, it started in SF so it has a local feel to it. They also have a regular feature, the Weekly Yelp, which covers upcoming events in SF as well as new clubs and restaurants.
Some of the places I've found on the site that I want to check out:
I went to another place I found on Yelp last night on my way to see Miguel Migs at Mighty. Kelly's Burgers was definitely a solid burger but I wouldn't say it's the best burger in SF. That title belongs to Joe's Cable Car Restaurant.
Miguel didn't start his set until 1am and by then I was already starting to feel tired. I really need to train myself to never show up at a club before midnight.
